Title: Sample feeding device
IPC: G01N1/00
Filed: 1979-12-28
Abstract: A device for automatically feeding samples to a graphite tube atomizer 14 comprises a turntable 22 accommodating a circular array of liquid vessels and driven by a servomotor 28. An intake tube 38,42 driven by a second servomotor 40 is movable between a position in which one end dips into a respective liquid vessel in order to suck in sample liquid and a second position in which the end extends into the sample inlet 16 of the tube 14 to discharge liquid into the tube. A control device 66 controls the movements of the turntable 22, the intake tube 35, 42 and also pumps 44 and 50 for sample and flushing liquid respectively, in accordance with a predetermined programme. A code disc turns with the turntable and acts as a turntable position sensor providing signals to the control device 66 which enable the latter to be programmed so as to bring the liquid vessels into the operative position for co-operation with the intake tube 38, 42 in any required sequence. <IMAGE>

Title: Automatic Steering Means for a Driverless Carriage
IPC: G05D1/02
Filed: 1980-01-29
Abstract: A driverless carriage has automatic steering means rendering the carriage capable of travelling in a straight line as well as performing a rotation about a vertical axis. It is provided with means for monitoring, during said movement, the position, with reference to the surface on which the carriage moves, of the axis of rotation of the carriage. Said means, which include at least one measuring wheel 18, 19 engaging said surface, are arranged on detection of a deviation of said vertical axis from a stationary position to produce a correction signal used for adjusting the steering means of the carriage so as to eliminate the deviation of said vertical axis from the proper position. Desired valve signals for the steering may be obtained from detectors 15, 16 (for forward and reverse respectively) of a leader cable 17 or from signals stored in a memory L. For the latter mode of operation, no leader cable is provided and distance travelled is obtained by integrating the signals from the measuring wheels. The speed of the vehicle is also controlled by comparing the wheel signals with a programmed reference. <IMAGE>

Title: Continuous casting of light alloys
Inventor: DOBATKIN VLADIMIR IVANOVICH
IPC: B22D11/114
Filed: 1981-07-01
Abstract: The method consists in pouring a melt and acting upon the melt using at least one ultrasonic radiator to purify the melt and to refine the structure of the strand solidifying from the melt; the ultrasound is applied uniformly throughout the cross-section of the melt at an intensity of 2 to 60 W/cm<2> as a function of the cross-sectional area of the solidifying strand. The radiator is immersed in the melt to a depth which is 1/12 to 1/4 of the wavelength of the sound in the material of the melt, and the temperature of the melt is 10 to 150 DEG C above the liquidus temperature of the material of the melt. Preferably, the melt passes through porous material the distance between this and the radiator being from 1/12 to 1/4 of the said wavelength.
Patent GB-2080906-A (GB)
Title: Cartridge for use with rock anchors
IPC: E21D20/02
Filed: 1981-07-03
Abstract: Reinforcing or fixing elements such as anchor bolts are anchored in a borehole with an anchoring cartridge in which a particulate liquid-settable solid component, for example a hydraulic cement, is contained in a liquid-impermeable casing, the solid occupying a volume which is less than the normal free volume of the casing and the cartridge being at least partially evacuated so as to cause the casing to be in contact with the solid component over substantially its whole length within the casing. This ensures that when the cartridge is immersed in an activating liquid, for example water, and the casing perforated, the activating liquid is drawn rapidly into the evacuated space adjacent the solid component over its whole length thereby helping to ensure the formation of a self- setting grouting composition of uniform strength when the cartridge is used.

Title: Vehicle load restrainer track assembly
Inventor: WHILLOCK ALAN
IPC: B60J5/06
Filed: 1981-08-05
Abstract: Support rail 11 is mounted adjacent a load-receiving space of a vehicle (e.g. above the body space of a lorry or on the floor of an aircraft's cargo hold), and carries track member 17 (in the form of slotted box section 19 defining channel 18) by means of arcuate extension 20 locating in slotted arcuate channel 15. Track member 17 is swingable relative to rail 11 as far as permitted by width of opening 16 in channel 15 and its channel 18 provides a track for wheels 25 of runners 24. A load restrainer (not shown), e.g. a net or a plurality of straps, is attached to bars 26 of runners 24, which bars 26 project through slot 21 of channel 18. The load restrainer may thus be easily drawn aside to permit access to the load-receiving space and may be swung sideways to facilitate enclosing a load in the space which load may be subsequently restrained when said restrainer is fastened down. <IMAGE>

Patent GB-2089068-A (GB)
Title: Numerical control machine tool
IPC: G05B19/18
Filed: 1981-10-29
Abstract: A numerical control machine tool has tools T1, T2 etc. mounted on the tool posts TP secured to the tool slide TS. Memories store the distance data between the original point WZ of a coordinate system set on a workpiece W to be machined and the positions of the edge tips of the tools positioned as selected. A reference position register holds the position of the tool slide TS, and a current position register indicates the current position of the edge tip of a tool to be used. When a tool is specified, the distance data stored in the respective memory is added to the content of the reference position register, and the result of the addition is set in the present position register, so that the tool slide TS is moved as much as the distance corresponding to the difference between the position instructed by the part program and the content of the current position register. Thus the tools T1, T2 etc. can be exchanged one after another while the coordinate system is maintained unchanged. <IMAGE>
